The Aero-Grow Rockwool starter plugs are a great way to get started in hydroponics, aquaponics, outdoor and indoor growing. The plugs come in trays of 25 and each plug is 40mm x 40mm x 50mm in size.
Aero-Grow Rockwool is unique, in that it is the only Stonewool in the market that is Formaldehyde free. We use a bio-based binder, called Ecose Technology, making the product a lot safer to use for vegetation and fruiting.
